Science/Strand III/Content Standard 1/Middle School/Benchmark 1
Benchmark Question: What are cells?
Focus Question: How can we prove cells make up
The class will brainstorm
what they already know about cells (KWL, small group, large group
discussion). Students will observe a variety of cell samples through the
use of printed material, videos, multimedia, and lab explorations. Students
will use a variety of scientific tools, such as microscopes and hand
lenses. Students will compile a log/journal and illustrate their findings
about cells from living things or once living things.
As a class, students will research
how scientists have developed an understanding of cells and how they
function in living things. Together, students will compile this information
to develop a class timeline.
The teacher should make sure
that students expand their understanding of scientific contributions to
include scientists from diverse populations (cultures, ethnicity, gender).
Such scientists might include the following:
Frank Young: conducted extensive
research in fundamental genetics of bacteria (1931-)
Barbara McClintock: Nobel Prize
Winner at age eighty-one; did research in genetics and mutations (1902- )
Ernest E. Just: studied cell
physiology and understanding life itself and evolution through the study of
Katherine Esau: an expert on plant
viruses; focused on research on cells and tissues that produce food for plants
